Document Summary

Humans: incredible power to modify & impact environment. Direct: actions have a clear & immediate impact. E. g. railway construction through forest = 500ha less forest. Impact triggers related impacts: often greater impact than direct, usually (cid:498)lagged(cid:495) in time. Natural hazards: threats od a naturally occurring event. Anthropogenic hazards: occur as a result of human interaction with the environment. Changing perspectives: (cid:853)(cid:852)(cid:852) years of hazards thinking in (cid:853) slide . 1930s-1960s: stop hazards from causing disasters (structural approaches) 1990s-present: unnatural hazards & human vulnerability (cid:494)unnatural(cid:495) hazards & disasters.
